Open source experts have hit back at a study published by the United States Computer Emergency Readiness Team that said more vulnerabilities were found in Linux/Unix than in Windows in 2005, labelling the report misleading and confusing. The report has attracted criticism from the open source community. Linux vendor Red Hat said the vulnerabilities had been miscategorised, and so could not be used to compare the relative security of Windows and Linux/Unix platforms.

I'll just say to you that there were no windows kernel-mode (ring0) shellcodes up until 8 months ago, and those for linux were written 7 years ago. And wanna know why? Because noone understood properly what windows kernel does

Class dissmissed.

And how is it that this invalidates my claim that open-source software is more prone to finding security flaws?
